COIN-CONTROLLED VENDING. IVIECHANISM.

Application filed February 24. 1922. Serial No. 538,941.

This invention relates to coin controlling operated mechanism fordispensing and other devices, and its objects are such as will behereinafter set forth.

The present application is in part a continuation of my applicationSerial Number y application also discloses mechanism -for the samepurpose, which is aniniprovement over that shown in my formerapplication. While 'this improvement dilers considerably :trom

the toi-mer device in details of construction, in the broader aspect thetwo structures are substantially the same, and :tor that reason.

they will be the subject of certain broad claims. The improved structurewill also be the subject ot certain specific claims.

The principal object of my invention is to provide a coin controlledmechanism :tor operatingl dispensing and other devices which will bestrong, simple ot constructionV and free from parts that are liable tobe injured or disabled by the severe and abusive use to which mechanismot the kind is commonly subjected.

Another object is to eliminate as tar as possible the' li ability toderan gement or injury by malicious or mischievously inclined persons;also to reduce as far as it is practicable the possibility of'operatingthe mechanism without first inserting a coin of the required kind vinthe receptacle provided for the purpose; also to provide for returningcoinsv to the operator in case they tail to release the device.

Another object is to provide a device whose various functions areetl'ected. by positive means, instead of depending upon the Weight.

et a coin or other equally delicate and uncertain mechanism.

Another object is to provide for registering the coins which actuallypass through the machine to the cash box, but to allow the machine to beoperated by the caretaker withoutthe use ot a coin and without theregister be-` ing actuated. Other objects will be obvious orparticularly pointed out hereinafter.

In the accompanying drawings,

`Referring now to Figure 1, I shall review briefly the vending device,so that the requirements 'for ar mec ianism to operate it will -bebetter appreciated. At the bottom of Figure -1 is shown a portion ot thebase plate 25 which carries the mechanism above. -rhis plate acts as acover Jfor the reservoir which contains the beverage to be sold.Attached to the under side ot thisiplate is a pump, vvhose piston rodisattached to a rack 26. Meslied with the rack is a gear 27, loos-elymounted on a transversely extendingshaft 28. Fixed to ioo the shaft injuxtaposition to the gear is a disk 29 which is provided with an arcualslot 30. A stud 31 lined in the gear eX'tends through this slot'and ashort distance past the disk. The reservoir, pump and piston are notshown.

The shaft is rotated forward and backward manually by means of a crank32. Turning the crank clockwise as it is seen in Figure 1, first rotatesthe disk 29 idly, but when the lower end of the slot iinpinges on thestud lfthe gear 27 is made to rotate with'the shaft, and thusvtlie rackis lifted, the pump piston being simultaneously lifted. Counterclockwise motion of the crank moves the rack downward after the upperend of the slot 30 has impinced on the stud 31. fore affords a limitedlost motion between the rack and crank, the purpose of which will appearpresently. The shaft 28 is ournaled in a pair of side frames 33, one ofwhich is seen in the ligure. At their upper ends these frames carry asuper base 34, on which is cari ricd a cup dispensing device 35 and a.stack of nested cups 36. The lower end of the stack of cups hangs downin a compartment which is formed by a semi-circular wall 37 and a. pairof segmental doors 38, which are mounted to swing inropposite directionson a common vertical axis. By means of a lever 89 pivoted at 10 to thesuperbase 34, and a cam (not shown) on shaft 28, the doors are openedwhen the crank is moved clockwise. same motion of the crank releaseslthe bottom cup, so that theoperator may remove it from the stack. Hethen sets the cup on the floor of the compartment under the spout- (notshown) Vand returns the crank to its normal position, as seen inFigure 1. The forward or clockwise stroke of ythe crank caused the pumpcylinder to be filled with f liquid from the reservoir and ontlie returnstroke of the crank this liquid is discharged in Figures 1, 2 and 3, forpreventing operation of the crank unless a coin of required size hasbeen deposited in the coin chute.- It

is understood that the mechanism shown in Figure 1 is to be enclosed bya hood. This hood is provided with a slot which registers with a chute50, whereby a coin is carried to a coin carrier 51 mounted on the disk27. This carrier is a small lever or pawl, pivoted at 52 to the disk 29.A spring 53 presses the pawl toward the perimeter of the disk, its-movementin that direction being limited by a tail 54 on the pawliiiipinging onl a pin 55 setin the disk. The pawl 51 is lseparated from-the disk by a washer (not shown) surrounding the pivotal screw 32, asufficient disparallel plates 57.

The slot there- This tance' to provide a. space between the disk andpawl adapted to receive a coin. An inwardly bent lug` 56 on the pawlacts as aV temporary support for the coin. In the same vertical planewith the coin as it reposcsin the carrier, is a chute composed of twoThese plates extend upward and the level of the shafts axis carry ascrew 58, the end of which acts in the. beginning as a support for thecoin. 1n Figure 1 a coiii is shown with dotted lines, confined betweenthe pawl. and disk. and resting on end of the screw 58 and the lug 56.

Loosely mounted on the shaft 28 is a lever 60, one end of which isconnected by a link 61 to a locking member 62. This member is a levermounted to rock on a lined center 63, and isvprovided with a hook 64,which, when the lever is rocked to th-e position it occupies in Figure 2is adapted to catch the stud and arrest the gear 27. The lever is placedon the shaft a sufhcient distancefroin the disk 29 to permit the pawl 51and all parts associated with it to pass the lever without touchn ingit. But the free end of the lever is provided with a laterally extendinglug or tooth In Figure 3 a portion of the lever is broken away, leavingthe tooth 65 in its normal position. Extending outwardly from the pawl51 is a lug, or tooth 66, this lug being iii the saine vertical plane aslug 65. When the pawl 51 is in its normal position, that is, when itstail 54 is engaged with the pin 55, it will iinpinge on the ing 65 whenthe crank is operated and rock the lever 60'. This throws ythe hook v64into the path of the stud 31, which arrest the crank when the stud imnpinges o-n 'the hook. This is what has occurred in Figure 2. When a coinof suii cient diameter is in the carrier, as in Figure 1, turning thecrank causes Athe coin. to wipe.

to as the abutment, is so adjusted that in wiping past the abutment thecoin, bearing against the lug 56, will rock 'he paw far enough on itspivot to permit the lug 66 to pass the lug 65 without touching it. Thisis illustrated in Figure 3.

The lug 66 having passed the lug 65 without touching` it, the lever G0and locking menibei' 62 remain stationary in the position they occupy inFigures 1 and 8, and the crank is permitted to continue its movementandv actuate the mechanism as previously described. A full-strokedevice, not shown in Figs. 1, 2 and 3, takes control of the shaft. afterit has passed the position it occupies in Fig. 2` and compels the shaftto turn clockwise the required distance before permitting it to rc-rturn, and then requiring it to return entirely home before it may beginanother cycle of operation. The fullstroke device must not take controlbefore the shaft reaches the point where it may be arrested, as inFigure 2. The timing of the full-stroke device will be considered moreat length in connection with the improved mechanism.

l shall now describe the mechanism for registering and disposing ofcoins according to their character. Between the plates 57 a lever ismounted to rock on a fixed axis, 71. ln Figure 3 one of the plates isremoved, showing the lever in full lines. At its lower end this levercarries a stud 72, which extends through a notch cut in one of theplates 57 and plays in a slot 62n in the lower end of the lever 62. f1When the lever 62 is in its normal position, as in Figure 3, the lever70 is in the position it occupies in that ligure. When a coin has passedthe abutment, assuming that it is of suficient size to secure thepassage of lug 66 past lug 65, the coin passes along the right hand sideof lever 70, as in Figure 3, and lights on a stud 73 which is carried bythe operating arm of a counter. rlhe coin is shown with dotted linessupported by the lever 70 and stud 73. An arm 75, ixed to a small shaft76, has a slot at its free end. A stud 77 carried by an arm dependingfrom a sliding member 78 plays in this slot, and when the member 78moves horizontally to the right the arm 7 5 is rocked clockwise. Bymeans not shown, andv which it is not necessary to describe, the member78 is moved to the right at each clockwise motion of the crank and tothe left upon the return stroke of the crank. Fixed to the shaft 76 isa'second arm, 7 9, having a slot and pin connection to a sliding member80, which is confined 'between the plates 57, and each time the arm isrocked as above 'described the member 80 is moved down and up. Themovements are l so timed that the coin lodges on the counter stud 73before member 78 moves. The sliding member 80 impinges on and pushes thecoin down between the lever 70 and stud 73, with the result that the armcarrying the stud is rocked on i'ts axis." Shortly after the coin hasbeen pushed past the stud the beveled end of the sliding member 80engages the st-ud andv continuing its downward movement the slide rocksthe counter arm back to its original position. And thus a coin whichsecures the release of the crank, or to be more exact, a coin whichprevents the arrest of the crank is reg"- istcred on the counter. Thecounter operating mechanism is all shown in dotted lines in Figures 1and 3, but it is very clearly shown. Having passed the counter stud thecoin drops into the cash box 81.

As is shown in Figure 2, movement of the locking member 62 to theposition for arresting the crank, throws the lever 70 to a positionwhere a coin dropping between the plates 57 will descend on the lefthand side of the .lever and is conducted to the chute 82 (Figure 1).Then the hood is on the machine this chute registers with a smallreceiver set in the side of the hood and coin dropping into thisreceiver is accessible to the customer, In order to reduce as much aspossible the opportunity for operating the machines with other than agood coin, the abutment screw 58 may be set so that any coin evenslightly below the standard fsize will fail to get the lug 66 past thelug 65. This arrangement may result occasional-ly in a good coin beingrejected, but since the coin is returned to the prospective customerthis is not a serious matter.

l shall now proceed to describe the improved mechanism, referring tirstto Figure 4,

which shows vthe part-s in their normal posi-y tions. rlhe crank 32 isnot shown, but it is to be understood'that it is fixed to shaft 28. Thepump (not shown) is operated by a rack 26 and' gear 27, the latter beingloosely mounted on the shaft 28 as before. Rigidly fixed to the shaft 28is a cam 100, taking the place of the disk 29'in the old construction,the cam Yhaving' an arcual slot 30 in which a. stud 31 in the gearplays, as before. A locking member 101, mounted to rock on a stationarycenter 102, is arranged to arrest the crank when it is operated withouta coin having been inserted in the slot, or in case the coin is toosmall. The mechanism for this purpose will now be described Mounted onthe superbase 34 is a frame 105, which carries a pair of plates 106 and107,v the latter being circular and provided' with a laterally extendingannular flange 108, convert-ing the plate V107 into a. sort of housing.

' See Figs. 6 and 12. A disk 109 is mounted to rotate in this housing,it being provided with a laterally extending stud 110 which is journaled in the plates 106 and 107, and the frame 105, a cotter pin 111being inserted in the end of the stud. A lever 112 fulcrumed on astat-ionary pivot 113`carried by the frame 105, is connected at itslupper end to the disk 109 :by a link or pitman 114. At its lower end thelevercarries a roller 115 which normally lies in a deep recess formed inthe periphery cam 100. See Figure 4. l/Vhen the shaft 28 'is rotated theleft hand side, 116, of said recess acts as a cam and rocks the lever,the roller riding up the cam to the first step, 117, as in Fig. 7. Thestep 117 is concentric and permits the cam to rotate a short distancewithout moving the lever then a second cam, 118, engages the roller androcks the lever still farther, raising the roller to the second step,which is the concentric perimeter 119 of the cam. lThe pitman 114 isconnected to the disk 109 in such a way that rocking the lever 112rotates the disk. i

,A rectilineal plate 125 is arranged to slide radially in a suitableguide formed in the disk 109, the outer end of which plate is bentv toform a right angle, the bent over end carrying a small block. 126, whichl will hereinafter refer to as a pawlf7 A'stud 127 is fixed in disk; aspring 129 carried by the disk bears on this stud and constantly pressesthe pawl toward the flange 108. Normally the pawl lies quite close tothisiange, as in Figure 4,

lthe flange being partially cut away to allow the plate to cross it. Asthe plat-e moves with the disk when it rotates, the flange is cut forapproximately one-third of the circumference of the disk. See figure 12.

A lever 130 is loosely mounted on the stud 110 between the frame 105 andplate 106 (see Fig. 6) one end of which lever, 131, is bent to formaright angle, thereby bringing it into the plane in which the pawl. 126moves; it is also in the Zone in which the pawl moves when in its normalposition with reference to the disk; that is, in the position shown inFigs. 4 and 5. At a point 132 a rod 133 is attached to the lever 130, bywhich the lever is connected to the locking member 101. It will now beseen that when the shaft 28 is rotated `clockwise the lever 112 will berocked by the f cam 116, from the position it occupies in Fig. 4,Causing the disk 109 to bc rotated, tne pawl 126 moving with the disk. Acomparatively slight movement of the shaft is sufficient to rotate thedisk to where the pawl 126 will impinge on the end 131 of the lever 130,and continued movement of the shaft causes the pawl to rock the lever.Through the medium of the rod 133 the locking member 101 is rocked andits hooked end is thrown into the path of movement of the stud 31carried by the gear. The movement of the parts is so timed that by thetime the end of the slot 30 impinges on the stud the hook is in posi'-tion to prevent movement of the gear and the movement of the'shaft isthus arrested by the stud bearing against the hook of the lockingmember. This is what has occurred in Figure 5. A

I will now describe the mechanism whereby a coin of proper size movesthe pawl 126 outward, so that it will pass the end 131 of the leverwithout touching it, as in Figs. 9 and 10. The disk 109 is provided witha pocket 140 for the reception of a coin. When the disk is in its normalposition the open end of the'pocket faces and is quite close to the wallof the hood. This is best shown in Figure 12, where the the hoodisindicatedby theline 141. Attached to the hood is an escutcheon plate142, having a slot 143 opposite the coin receptacle 140. The plate 106carries a flange 144, which is folded over at its outer edge to form aguide for a shutter 145, used to close the coin slot when the reservoiris empty. At 146 the flange 108 is cut away sufficiently to allow a cointo be inserted in the receptacle. See also Fig. 4. The portion of theflange from the cut-away 146 to the point 147 forms an abutment 148,against which the coin wipes as the disk rotates, from which point theflange is tions allotted to it.

cut away so that after the coin has passed the abutment it may leave the'receptacle 140. Referring to Fig. 4 it will be seen that one edge ofthe coin 149 in the receptacle lies against the end of the plate 125,while the opposite edge extends beyond the zone in which the abutmentlies. Therefore, when the coin impinges on the corner of the abut ment,early in the movement of the disk, it is pushed deeper into thereceptacle, and being against the end of the plate 125 it moves theplate outward. lf the coin is of sufficient y diameter the pawl 126 willthus be moved far enough to cause it to pass outside of the end 131 ofthe lever 130. The lever 130 and locking member 101 being undisturbed,the shaft 28 is permitted to complete its normal cycle ofy operation,and perform the various func- If the diameter of the coin isinsufficient to move the pawl far enough to pass the lever 131, thelever is moved by the pawl ust as though no coin had been deposited inthe receptacle, with the result that the locking member 101 is broughtinto action and thek movement of the shaft is arrested, in the mannerpreviously described. The pawl 126 is attached to the plate 125 withscrews 150 and an opposing set screw 151, by means of which the positionof the pawl with reference to the plate can be varied. By means of thisadjustment a cer* tain minimum for the diameter of a coin necessary tosecure theoperation of the machine may be established and a coin vofless diameter will then fail to secure its operation.

Coins which secure the operation of the machine; in other words,acceptable coins, are conducted to a cash box 155, by means of a chute156. Above the superbase 34 the chute comprises a part 157 of the frame,a plate 158 secured thereto with screws, and a plate 159, hinged at 160to the part 157,. It isto be understood that the plates 158 and 159 aresufficiently removed from the vframe 157 to vpermit the coins to passbetween them.` To prevent rejected coins, that is, coins which do notsecure the operation ofthe machine, from entering the coin chute, theplate 159, which will be called the deflector hereinafter, is providedwith a laterally extending bifurcated wing 161, in which plays anextension 162 of the lever 130. l'Vhen the lever 130 is rocked becauseof the coin being too small in diameter, the defiector is rocked on itsaxis by the extension 162, to the position shown in Fig. 6. Then whenthe coin drops out of the receptacle it is deflected from the main coinchute to a return chute 163. See also Fig. 5 where the operation of thedeflector is illustrated. In Figs. 4 and 5. a portion of tue cover ofthe return chute is broken away to make the construction more clear.

A full-stroke device is arranged to come into action, or take control,as l prefer to eX- press it, after the shaft 28 has passed the step 117.

ate with the teeth ot the segment. is the device is well ilustrated inFigs. 4, and 7 and is oi an old and well known type, itineed not befurther described here. The tullstroke device is so timed that it cannottake control until after the shaft has passed the point at which it isliable to be arrested by the locking member 101. lVhen the shaft 28 isnear its normal or home position as in Fig. el, it is urged towardsaid-home position'by a spring 167, one end oit which is attached to theJframe 33 and the other to the lever 112. As this spring tends to movethe lever to its normal position, theroller bearing V'against the camtace 11G acts to turn the sha tt counter clockwise. But on the otherhand, the return ot the lever 112 andv its associated parts to Vtheirnormal position does not depend upon the spring. A horn 168 projectingtrointhc cam 100 engages the roller and returns the lever 112 to itsnormal positionf By relierring to Fig. 1 it will be seen that lthe crankis in such a position when at home ,that its weight tends to return theshaft to its home position. 1

1t is important to prevent the coin leaving the receptacle 140 untilafter the full-stroke device assumes control, as it is then impos# siblefor the purchaser to lose his coin and 'tail to obtain his purchase fromthomachine. l? or this purpose a laterally7 extending ear 170 is carriedby the detiector 159. r1`his ear-,or retainer, is seen in plan in y6,but its tunetion is best illustrated in Fig. 7. .1n that tigure the.full-stroke device has just. taken control; that is, the pawl 166 hasjust dropped behind the Atirst tooth ot' the segment 165, while the coinis still held in the receptacle by the retainer 170. The lever roller isresting on the step 117 and the cam 118 has not lvet reached the roller;so the disk 109 is stationary and has been since the roller ran onto theThe cam 118will rock the lever and rotate the disk 'tar enough to carrythe coin past the retainer.V In Fig. 5 the coin having been rejectedbecause ot its insulhcient size, is enabled to Vdrop tromthe receptaclebecause the movement ot the 'detlector by the extension 162 hasremovedthe retainer from the. `,ilane ottlie receptacle. l 1V hilo coinswill usually drop trom the receptrfrcle by gravity, l provide an ejector.by

theyare ejected positively. This cons ofV a lever 175 pivoted to thedisk 109,v having a lateral lug 176 which plays in a slot 177 viiiithedisk. the 'lugq extending across the coin receptacle 140. The end of theplate 125 bitureated and in Fig. et it .is seen that the purpose of thisis to provide 'for the retirement ot the lng 176 to allow the coin tolpiege directly Anon the end othepl-ate. De

co-oper-y pending from the pitman 114C is a finger 178, adapted toimpinge on the ejector as the roller rises from the step 117 toperiphery 119 of the cam and during this latter stage of the movementofthe lever and disk swing thev ejector toward they periphery of thedisk, forcibly ejecting the coin if it does notdrop out of the pocket bygravity. A. linger 179 projecting` laterally from the ejector is firstengaged by the `iside of the linger 17 8, as in Figs. 7 and 10, whichproduces compara-r tively slow movement ot the ejector. During` thesecond stage of the movement of the pitman and disk the end of thelinger 178 engages the ejector directly and throws the coin outquickly.' TWhen a coin of insufficient' diameter inserted the movementoit the shaft 28 is arrested before the pitman .and disk'have movedsufficiently to actuate the ejector'. rllhe'ejector is then actuated bya liorn^v180 -which` projects from pivotally mounted plate 181. r1`hisplate carries an-` other horn, 182, whose end is confined between thedeflector 159 and an ear 183 carried by the deflector. W'hen thedetlector is thrown to the position it occupies in Figs. 5 and 6, theplate 181 is movedwith` it bringing the horn 180 into the plane 01"movement of the ector. Coming into engagement withthe horn 180 the ectoris moved to eject,` the coin, as in Fig. 5. YVhenthe coinf isofsuflicient size 'and the 'del'lectoriremainsin normal position,

the` ejector passes behindthe horn 180, as in Figs. and 11.v v i f The'mechanism 'for operating the counter is bestshown-inFigs. 7 and 8. Thecounter itselt1 is not rshown in either of these views but the shaft lonwhich the counter Wheels are mounted is shown in section at 190. Fixedto this shaft is an arm 191, carrying a stud'1921which extends into thecoin chute, normally standing in the position shown-in Fig. 7 throughthe action of a. spring193. When a coin dropsinto the chute it isarrested by the stud, as shown with dotted lines in Fig. 7. `Pivotallymounted on the iframe 157 is alever 194, which is provided with alaterally extending arm .195:1 This arnr is in -tlie path ofthe/racky26theupper rear corner otwhich i-s rounded, 'and' as: the rack ilorises' itengages the arm and rocks thelever as the rackdes'cends,isiengaged by a stud 198 projecting from the side *of the rack reviews.j i

lfilhile vthel mechanism enclosed 1n a hood lnipote from the observer asseen-in l,the several or casing which prevents access to it, thecaretaker is enabled to remove the hood for inspection and to clean oroil the parts. Inspectors or caretakers of such machines commonly carryslugs with which to test the mechanism. But these would operate `thecounter, which would then show an inco-rrect record of coins received.To avoid this the caretaker can trip the mechanism manually when thehood is orf. In the structure shown in Figs. 1, 2 and 3 he swings thecoin carrier with his finger while he moves the crank. Thus he can causethe tooth 66 to pass the tooth 65, as in Fig. 2. In the improvedstructure he needs onlyto push the pin 127 to the right far enough toenable the block 126 to pass lever end 181.

It will now be seen. that the apparatus above described is not onlypositive in its operation and free from parts or combinations o partswhich are liable to get out of order, but that it is to a marked degreewhat is called fi'ool proof. In at least two particulars it is adeparture from other coin controlled vending devices, as it employsnovel methods of effecting certain results. First, it is novel toutilize movement of the operating member of a-vending machine to actuatemechanism whereby movement Vof the operating member is arrested beforevenldition occurs, unless a suitable coin has beenv deposited in a Kreceptacle, and the term vending is here used in a broad sense, toinclude any coin controlled apparatus. Second, it is novel to registercoinsreceived in a vending machine by means of the coins themselves asthey pass to the coin box.

While I have disclosed ltwo structures for Vcarrying out my methodofcontrolling vending machinesit is not to be understood that I regardthese as the only ones by which it can be done; nor do I wish itunderstood that I consider the scope of my invention limited to theparticular details of constructionshown. The scope of my invention isonly limited bythe claims appended hereto. What I claim is as follows:

1. In a controlling mechanism for dispensing and other devices, amember' adapted to operate Vthe controlled device, a coin carrier movedby said member, a locking device adapted to arrestk the operatingmember; and a member' intermediate the coin carrier and said lockingdevice, adapted` to be engaged by the carrier when the operating memberis moved without a coin in the carrier and caused to move the lockingmember intoposition for arresting the operating member. v A `2.
